Figure 8 is a broken perspective view of an assembly embodying a greater number of carbon sheets.

The use of the present carbon holder is with continuous-form stationery such as illustrated in Figure 1. Herein, the stationery S is zig-zag folded along cross lines of weakening in the stationery strips. The thickness of the stationery, the folds therein, and the relative position of one fold to another have all been exaggerated for purposes of clarity of illustration. The uppermost stationery strip 9 has a carbon sheet 10 held in manifolding assembly with the next lower stationery sheet 11 and the same is true for the next two carbon sheets 12 and 14 with respect to the underlying stationery sheets 13 and 15, all illustrated in Figure l. The carbon sheets in use are of a good grade for repeated use and ripice vthus are shifted longitudinally of the Astationery strips' into register with successive form lengths.

The structure of the carbon holder may best be under- Stood ,from a description of its method of manufacture. 5 An elongated sheet or strip of .paper stockmaylbedprepared with an edge applied film 16`preferably of a-tear- ]iroofpc'ilyester film. This lm will render the paper `stock `proof against tearing or cutting 1by 'the stationery. Thereafter, slots such `as 17 and 18 are cutso as to extend across the strip and leave individual blade segments suchas 19, 20and 21. 'Theseblade segments orportions ,extend across the strip in spaced vparallel relationship. The slots are generally slightly narrowerthan the blade segments. It should be understood that Figures 5 through #7 show a bar having three bladesegments, thebarhaving been separated from an elongated sheet vhaving many times this many bIadescgmentS. It is preferred to use only threeblade segments in a bar in order to cut down on the overall width of the carbon holder.

`After the base of the `holder inthe form of-.thebar :such Vas 22 Y(Figure 6) is prepared, each blade portion is reinforced land stiffened by the applicationofa flat clock-steel wire ,23 positioned overthe length and gen- `erallytherniddle .of the blade portion.' To aid in-.the placement of -the steel yreinforcing fmembers,Y they may be threaded Athrough pairs of openings 24 which Ytemporarily hold thesteel wires in place. In Figure6,two

-of .the blades are shown reinforced by the lsteel wires, `:whereas in Figure 7 ,all threefof the bars are :soreinforced. gThe centerbar may, in some applications, .be usuicientl-ystiff to avoid.the necessity `of reinforcement.

The'strip from whichthe bars of the holder lwerecut I.was -preferably5provided with a delayed action v heatffieal ...adhesive :such as is commercially available. This Iaglhesivemaybe used to provide an easy andready lassembly of the carbon sheets, blade portions of the holder @and reinforcing wires. The bar is assembled Y.so fthat ;Ih e`rearward -edge of a carbon sheet -is in alignment with each blade portion. 'Referring to Figure 3, thefcarl.liiolrsheet hasits rearward edge v1li in alignment:V with the edge of the blade 19. Carbon sheets 12 and 14 are similarly related to -blades '20 and 2.1, respectively. -lt is preferred that the'wire 23-be between thecarbon :sheet d0 andthelb1ade 19 lOncefassernbled, as illustrated in Figure .3, heat'may be applied to render the adhesive iactive vthus making-gan assembly. `The carbon @holder `is now ready for assembly on continuous-form stationery.

The assembly is accomplished as .shown in Figure 2. YThe lowerrnoststationery strip is laid out-flatand :the carbon holderplaced on top -thereof Lcenteringrthe Aholderslaterally of the strip. vThe next kstationerygstrip 13 is threaded through the slot `r1*7 immediately above fthebar 19. Thisplaceszit in position to be under the wnext xcarbon sheet 12. The next stationery sheet 11 is likewise threaded'throughthe .lslot'l'S Vso as :to be under carbon sheet 10. The:uppermost stationerysheet'S :is then simply laid over the assembly, completing the mani` folding set.

Once a set of lforms are lled in with the desired writing, the carbon holder and its `attached carbon sheets may be manually moved by sliding the holder lengthwise of the stationery. The ends of the -bar which integrally join the blade portions form tabs 25. The lm 16 covering the tabs may extend beyond the edges of the slots so that the die cut of the slot passes through the film. In this way the stationery will not ordinarily tear or cut the tab, or in any way impair the structure of the holder.

When the stationery is fed about a platen the holder passes readily through the pressure rolls. The paper stock of which the holder is made may be only .008 thick and the steel wire may have about the same thick copies.

As illustrated in Figure 8, a lower carbon holder'26 is hingedly joined to an upper holder 27 yby a tape-like flat hinge 28 joining the adjacent tab portions 29 `and 30. A

, pressure sensitive tape 31 may join the ,opposite tabs y32 and 33, once assembled. In use, the two` holders are hinged out fiat side-by-side; the lower holder is threaded on the lowermost strips of the stationery and thereafter the upper holder 27 is laid over on top of the 'part assembly already made and the upper stationery strips threaded therein. The pressure sensitive tapes 28 and 31 maintain the two holders 26 and 27 together as a unit and they operate in precisely the same manner asv described above. Each of the holders 26 and 27 is provided with carbon sheets C and in essence, consists of one of the carbon holders previously described.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom for some modifications will be obvious -to those skilled in the art.

I claim: l. A carbon holder for use with continuous-form sta- `tionery, comprising: an yelongated bar of sheet material, having at least a pair of spaced blade portions joined integrally at the ends of the bar, said blade portions being separated by cutouts in the bar extending across the major Xportionof the bar length; an elongated flat metal wire secured to and extending in superposed relation with, j

each blade portion and terminating adjacent the ends of ksaid -blade portions; separate sheets of transfer material each having an edge secured to one blade portion pro- 'viding a plurality of transfer sheets in superposed relation, said cutouts providing spaces for threading continuous strips of lstationery between the transfer sheets' into manifolding assembly relation, the ends of said bar being spaced to provide exposed tabs at the sides of the manifold assembly and said at wires and blade portions holding the transfer sheets for unitary sliding blade portions and the metal wire is held captive be-Y tween the transfer material and blade portion, said wire having a width less than the blade portion and being positioned centrally thereof. t 3. A carbon holder as specified in Aclaim 1 wherei the ends of the bar are coated with a tear-proof poly.

ester lilm and said cutouts extend into an edge of said iilm to prevent stationery strip from severing the blade portions from the bar.

A carbon holder for use with continuous-form staslots forming longitudinally extending blade portions v tionery, comprising: an elongated bar of relatively Vlight-` weight sheet material having longitudinally extending spaced laterally apart, tab portions at the ends of the bar integrally joining said blade portions; a flat wire stiffener extending over the length of each blade portion and adhesively secured thereto; a plurality of transfer sheets one secured to each blade portion and extending laterally therefrom, said slots providing space for threading stationery strips between the transfer sheets into manifolding assembly, Vsaid tab"y portions providing hand holds for sliding the carbonholder lengthwise of sta- -tionery strips threaded in Vthe holder.

5. A carbon holder for use with continuous-form stationery, comprising: an elongated bar of relativelylightweight sheet material having longitudinally extending slots forming longitudinally extending blade portions spaced laterally apart, tab portions at the ends of the fbar integrally joining said -blade portions, said tab portions having a tear-proof polyester iilm thereon extending to the ends of said slots; aflat wire stienerA extending over the length of each blade portion and adhesively secured thereto; a plurality of transfer sheets one secured to each blade portion and extending laterally therefrom, said slots providing space for threading stationery Astrips between the transfer sheets into manifolding assembly, said tab portions extending laterally of a manifold assembly including said transfer sheets for manipulating the holder slidably along stationery strips in said assembly and said lm on said tab portions protecting the holder from accidental tearing.

6. A carbon holder as specified in claim 5 wherein a pair of said elongated bars are arranged in superposed relation and means Vhingedly connect one pair of superposed tab portions-for swinging -movement of one bar and its transfer sheets into and out of said relation, and means for removably securing the opposite pair of tab portions together to form said manifolding assembly with stationery strips. 'I

7. The method of forming a carbon holder for use 'with continuous-form stationery, comprising the steps: applying a tear-proof film to lateral edges of an elongated strip of sheet material having a heat seal adhesive coating thereon, die cutting the strip of sheet material laterally thereof -to form alternate narrow slots and bladeportion extending across the strip'leaving integral side bands, temporarily positioning a thin elongated metal .wire to extend lengthwise over each blade portion,` positioning a plurality of carbon sheets, each with an edge overlaying a blade and said metal wire, then applyingheat to adhere `said carbon sheets, metal wires and blade portions together, and then severing the margins of said sheet between blade portions to provide a holder with a desired number of carbon sheets thereon.
